Synopsis by Hal Erickson
Rin Tin Tin wannabe Ranger is the canine hero of When a Dog Loves. The story gets underway when both Ranger and a valuable necklace turn up missing. The dog is rescued by a small boy who adopts him as a pet, never realizing that Ranger's owners have offered a huge reward for his return. Meanwhile, hero Harold Goodwin finds the necklace around the neck of his sweetheart Helen Foster. Both Goodwin and Foster subsequently run afoul of jewel thieves, but Ranger comes racing to the rescue. Director J. P. Gowan performs yeoman duty trying to make sense of the herky-jerky plotline.
